LEWIS E. WATERMAN, OF ROCKFORD, ILLINOIS, ASSIGNOR TO EMERSONMANUFACTURING COMPANY, OF ROCKFORD, ILLINOIS, A CORPORA- WEEDER.

SPECIFICATION forming part of Letters Patent No. 791,522, dated June 6,1905.

Application filed Nove be 16, 1903.- Serial No. 181,456.

To a whom it may concern.-

Be it known that I, LEWIS E.W ATERMAN, a citizen of the United States,residing at Rockford, in the county of Winnebago and State of Illinois,have invented certain new and useful Improvements in Weeders, of whichthe following is a specification.

The object of this invention is to construct a weeder attachment inwhichthe knives are supported by two bars having a pivotal connection in amanner to swing horizontally and movable in unison by a movement imparteto the bail connecting the bars.

In the accompanying drawings, Figure 1 is a perspective View of acultivator-frame supporting my improvements. Fig. 2 is a side elevation,partly in section, of one of the pivoted bars. Fig. 3 is a plan view ofone of the pivoted bars in which the bail connection is removed. Figure4 is'a vertical section on dotted line a, Fig. 2.

My improvements are applied to the frame of a riding-cultivator, and inthe drawings only so much of the cultivator-frame is shown necessary togive a clear idea of the relation of my improvements thereto.

To the tongue 1 are connected the side bars 2. and extending rearward lythereof. An axle 3 has a connection with the bars 2. Aseat 4 issupported by the bars 5, connected to the cross-rod 6. The bars 5support a toothed segment 7 and to which is pivoted a hand-lever 8,having dogs 9, engaging the teeth of the segment. J

To the under face of the tongue is pivoted a yoke 10, having its endsprovided with transverse slots 11. To one arm of the yoke is pivoted abar 12 at the point 13 and has an adjustable connection with the slot11. An arm 14 has a pivotal connection withthe other arm of the yoke andadjustable by means of the slot and a bolt passing through the slot.These bars 12 and 14 extend downwardly and rearwardly, their sections 15and 16 lying substantially parallel and horizontal. Each of the bars 15and 16 support two knives in a manner, that they may be moved toward andfrom the center of the frame, and a description of one set in itsconnection with the bar- 12 will answer for both, the samereferencenumerals applying to both.

To the bar 15 are secured two plates 17 and 18, both extending upwardlyand having perforated ends.

the tubular extension 19 and has a knife 21 secured to its lower end.The upper end of the standard extends through the plate 18 and has asegment of a miter-gear 22 located in connection therewith. Thissegmental gear has an extension 23 and a reduced upwardlytubular portion24. A yoke composed of the upper arm 25, lower'arm 26, and rearwardlyextending arm 27 has a connection with the standard 20 by the rear arm27, clamped in connection therewith by the bolts 28. The upper arm islocated over the tubular portion 24 of the segmental gear 22 and clampedin connection with the extension 23 by the bolt 29 and adjustable inconnection therewith by reason of the curved slot 30 in the extensionthrough which the bolt passes. The free end of the rearwardly-extendingarm 17 supports a standard 31 in a manner to permit of itsvertical andaxial adjustments. This standard 31 supports a knife 32 at its lowerend. The standard 20 has a vertical and axial adjustment in itsconnection with the lower arm 26 of the yoke.

The upper ends of the plates 17 and 18 support a bracket 33 by the bolt34 extending through the parts.

the teeth of the segmental gear 22, and has a rectangular socket 36 atits upper end.

A bail has a curved center portion 37 and horizontally-extending ends38. One of the ends of the bail is located in the socket 36 and held inan adjustable manner by the bolt 39. The other arm of the bail isconnected with the socket of the bracket supported by the bar 16, sothat the bail forms a connection between the two bars 15 and 16 in amanner that the bars may be adjusted toward and from each other to varythe distance between the two sets of knives.

To the upper end of the center portion of the bail is pivotallyconnected a rod 40, and

A plate has a tubular depcnding extension 19. A standard 20 is locatedin This bracket has an extension provided with teeth 35, meshing withthe other end of the rod has a pivotal connection with. the hand-lever8.-

To the rear end of the extension 15 isconnected a rod 41, its upper endhaving a connection with the axle by the link 42. (Shown in dottedlines.) The extension 16 has a rod 43 connected thereto and a.connection with the axleby the link 454.. (Shown in dotted lines.)

Handhelds 45 have a connection with the rods.

by means of the foot-loops 16 they can be moved transverse to the lineof'draft as usual in riding-cultivators and can be held suspended.

By means of. the hand-lever 8: and rod con-- nection with the hail thebail can be' moved on its pivotal connection with thearms 157. and 18,connected to the barsal5=and'16..v ment will rock the teeth; 35, whichen gage the segmental toothed: gear'QQand will; move it on its; pivotalcenter,,and asthe upper arm 25. has a'segrmentaltoothed gear. thedownwardexten sion: 27,.carrying: the knife 32, and the standard. 20,carrying the knife 21 will be moved axially, the'stand'ard 2O acting as:the center, and by, movingthe hand-lever forward from itscenter positiontheextensienswill be moved toward each other,.anearward movement of thehand-lever will separatethein, and they" portingrframe, frame havingia.pivotal con-- nection. with. the mainframaand composed of two branches,each branch supportmga pivoted bar, a knife supported by each bar; a
